头颅CT资料库在中医住院医师规范化培训中的应用研究

Application of head CT scan database in standardized training of traditional Chinese medicine residents

目的 探究基于“异病位、多时态、多维度”头颅CT资料库的头颅CT判读培训方式在中医住院医师规范化培训中的教学效果。方法 选取北京中医药大学东直门医院2019级中医住培医师为试验组,进行基于“异病位、多时态、多维度”头颅CT资料库的头颅CT判读培训;2018级中医住培医师为对照组,采取传统的CT读片和理论授课方式进行培训,通过调查问卷和统计学分析比较2组中医住培医师的技能考核成绩,判断该培训方式是否有效。结果 通过对试验组随机发放的60份调查问卷显示,认为基于“异病位、多时态、多维度”头颅CT资料库的头颅CT判读培训方式对掌握头颅CT断层解剖结构更有帮助的有83.3%;认为更有助于掌握脑梗死的CT动态演变的有75%;认为更有助于掌握脑出血的CT动态演变的有90%;认为可提升脑梗死的定位诊断和病情预判能力的有75%;认为可提升脑出血的定位诊断和病情预判能力的有86.7%。在北京市中医住培技能考核试卷中发现,试验组得分为2分、1.5分及以上的人数比例明显高于对照组,差异有统计学意义(P<0.05)。结论 基于“异病位、多时态、多维度”头颅CT资料库的头颅CT判读培训方式,有助于提高中医住培医师的头颅CT基本诊断、定位定性及病情预判能力。

Objective To explore the teaching effects of the training method of head CT scan interpretation making use of the multi-lesion,multi-temporal and multi-dimensional head CT scan database in the standardized training of traditional Chinese medicine(TCM)residents.Methods The TCM residents of the Class of 2022 at Dongzhimen Hospital of Beijing University of Chinese Medicine were assigned to the experimental group receiving training of reading scans using the head CT scan database.On the other hand,the residents of the Class of 2021,as the control group,were trained using the traditional method of reading CT scans and lecturing on theory.The effectiveness of the training methods was evaluated by means of questionnaire survey of the experimental group and statistical analysis of the two groups′skill examination scores.Results The 60 responses to the survey questionnaires randomly distributed in the experimental group showed that 83.3%of the residents believed this training method was conducive to mastering the sectional anatomy of head CT scan;75%the dynamic evolution of cerebral infarction reflected by the scans;90%the dynamic evolution of cerebral hemorrhage;75%thought that it could improve their ability of lesion identification and prognosis of cerebral infarction;and 86.7%cerebral hemorrhage.In the Beijing Traditional Chinese Medicine Residence Training Skill Assessment,the number of students who scored between 1.5 and 2 in the experimental group for the relevant question were significantly larger than that of the control group with statistical significance(P<0.05).Conclusion The training method based on“multi-lesion,multi-temporal and multi-dimensional”head CT scan database could improve TCM residents′ability of preliminary diagnosis,lesion detection,accurate diagnosis and prognosis based on CT scan reading.
